"Talking about venture capital, business angel (investors) - it's there, but it's still not really comparable to what's happening in the United States. But it's happening already, so I'm more positive (about Europe)," she said.

Her comments come at an interesting time for tech in Europe,with the European Union coming in for criticism over its stance on privacy in particular.

Google, for instance, is the subject of investigations in a number of member states over its privacy policies. The search giant has already agreed to remove some 170,000 links under Europe's controversial "right to be forgotten" rule.

The CEO of AOL (which owns TechCrunch), Tim Armstrong, told CNBC that such rules and regulations would have an impact on companies looking to do business in Europe.

"It will have an effect on business in those countries, but overall the opportunities are still bigger than the legal issues around privacy and taxes," he told CNBC at the TechCrunch conference on Monday. "It's much better to do business with other countries and figure out how to work with them, and that's what we're focused on."

"When you think about the future of media and technology, Europe has a big role to play," he said. "While the overall economy may be up and down – and I think it is up and down right now – the tech sector is very strong."
